Thyroid Cancer Underlying Cause

The cause of thyroid cancer is unknown, although genetics may play a role.

Genes control the functions inside a cell. Special genes control how cells divide and grow. Cancer occurs when the damaged genes stimulate the cell to multiply out of control. The exact cause for this damage is unknown.


  • DNA
  • Genes on chromosomes
  • Cancer cells
  • Cancer cell division

Cancer cells can develop from any of the cells in the thyroid gland. The cells can spread through the lymphatic system or the bloodstream.
